However, in this case, the copper alloy is not intended to come into contact with the rotating component; it is simply an intermediate layer, normally around 0.30-0.38 mm (0.012-0.015 in) thick between the backing and the soft metal alloy (often called white metal or ‘Babbitt’) that forms the actual bearing surface. This type of bearing construction is known as ‘tri-metal’ and has been described in previous RET-Monitor articles by John Coxon and Eric Smart.
